Pneumatic dilatation or balloon dilatation is also typically done at the time of endoscopy or fluoroscopy. A balloon is inserted in the deflated form into the area of narrowing. It is then inflated with air to a certain pressure that is pre-set for a given circumference.
In balloon (pneumatic) dilation or dilatation, the muscle fibers are stretched and slightly torn by forceful inflation of a balloon placed inside the lower esophageal sphincter. There is always a small risk of a perforation which requires immediate surgical repair.
Finally, pneumatic dilatation of the esophagus, which is an endoscopic technique where a high-pressure balloon is used to stretch the muscles of the LES, can be performed to improve symptoms, but again no clinical improvement is seen in regards to motility.
Dilatation can produce some temporary irritation. A short course of proton pump inhibitor therapy may decrease aggravation by stomach acid reflux into the esophagus. The duration of the benefit of dilation varies, but may be from months to years. Dilation may be repeated if narrowing recurs. [citation needed]
Minnesota four-lumen tube, with esophageal and gastric balloons, and esophageal and gastric aspirates. Balloon tamponade is considered a bridge to more definitive treatment modalities, and is usually administered in the emergency department or in the intensive-care unit setting, due to the illness of patients and the complications of the procedure.
Megaesophagus, also known as esophageal dilatation, is a disorder of the esophagus in humans and other mammals, whereby the esophagus becomes abnormally enlarged. Megaesophagus may be caused by any disease which causes the muscles of the esophagus to fail to properly propel food and liquid from the mouth into the stomach (that is, a failure of ...
Dilatation of benign oesophageal strictures using semi-rigid bougies existed long before the advent of flexible endoscopes. [11] Since that time oesophageal dilatation has been carried out using either bougies or endoscopic balloons, and can be used to treat benign oesophageal strictures and achalasia .
Botulinum toxin, which inhibits acetylcholine release from nerve endings, injected above the lower esophageal sphincter may also be used in the treatment of DES.Small studies have suggested benefit from endoscopic balloon dilation in certain patients, but all of the above have a low percentage of success in treating the condition; whilst the treatments work in some sufferers, it does not work ...
